Uncovering Ancient Fire Traditions During the Last Glacial Maximum
Learning to control fire was a game-changer for ancient humans, who could use it to cook food, see at night, and endure cold weather, among other things. This skill dates back at least a million years and has proven pivotal throughout human history, especially during certain times.
The Last Glacial Maximum (LGM) was the iciest part of Earth’s current ice age, lasting from about 26,500 to 19,000 years ago. Despite the extreme cold during this period, there is limited evidence of humans using fire. A recent study aimed to unravel this mystery by examining three ancient fireplaces found at an archaeological site in Ukraine, dating back to the LGM.
These hearths shed light on pyrotechnology in the late Upper Paleolithic, a time when fireplaces were surprisingly rare in the archaeological record. Previous research indicates that fire played a crucial role in the lives of Upper Paleolithic people, enabling activities like cooking, tool-making, and social gatherings.
The researchers suggest that the rapid climatic deterioration during the LGM, with cold and arid conditions leading to habitat loss, may have impacted the use of fire. However, the discovery of these hearths provides valuable insights into ancient fire traditions and the scarcity of hearths from this era.

Through meticulous analysis using various techniques, the researchers determined that the hearths were simple, yet capable of producing high temperatures. The predominant fuel source was identified as spruce wood, and the presence of bone remains in the hearths raised questions about their purpose.
These findings suggest that ancient humans had a sophisticated understanding of fire and its uses, adapting their techniques based on different purposes or seasons. The study highlights the importance of fire in the daily lives of hunter-gatherer societies and their ability to control and utilize it effectively.
While the study provides valuable insights into ancient fire traditions during the LGM, further research is needed to understand why evidence of hearths from this era is scarce. Factors such as soil disturbances or alternative technological solutions may have contributed to the limited presence of hearths in contemporary sites.
The study was published in Geoarchaeology.
